Sukhoi

Sukhoi is a Russian aerospace brand and aircraft design organization whose origins lie in the Sukhoi Design Bureau, established in 1939 under aerospace engineer Pavel Sukhoi. The organization became one of the Soviet Union’s important military-aircraft developers and later evolved into a corporate group involved in military aircraft, civil aviation projects, aircraft production and engineering services. Its design-office prefix, Su, is associated with a long succession of Soviet and Russian aircraft. The bureau’s first major production success was the BB-1 reconnaissance and light-bomber design, which entered service as the Su-2. During the Second World War, Sukhoi also developed the Su-6 armored ground-attack aircraft and other experimental designs. Although the Su-6 was not selected for large-scale production, its development demonstrated the bureau’s ability to compete in demanding military-aircraft programs. After the war, Sukhoi worked on jet fighters, bombers, reconnaissance aircraft and specialized military platforms, while also contributing to innovations such as ejection-seat systems, parachute braking and aircraft-control technologies. Sukhoi’s institutional history was interrupted in the late 1940s, when the design bureau was dissolved and Pavel Sukhoi returned to work under Andrei Tupolev. Following Stalin’s death, Sukhoi was allowed to reestablish his own bureau in 1953. The organization subsequently became associated with a succession of high-performance fighters and attack aircraft. Its later Cold War designs, including the Su-7, Su-17 and Su-25 families, established a durable reputation in combat aviation. The Su-25 became particularly associated with close air support, while later Su-27 derivatives created the basis for a large family of long-range air-superiority and multirole fighters. After the dissolution of the Soviet Union, Sukhoi faced the fragmentation and privatization of the factories and organizations that had previously operated within the centralized Soviet aviation system. During the 1990s it rebuilt an integrated industrial structure, brought together design and production assets, and expanded into civil-aircraft initiatives. The resulting organization included the Sukhoi Design Bureau, production associations in Novosibirsk and Komsomolsk-on-Amur, and Sukhoi Civil Aircraft. Its civil portfolio included the Superjet 100 regional airliner, while the company also participated in projects such as the Su-80 utility aircraft, the Su-38 agricultural aircraft and composite-wing work for the Irkut MC-21. In February 2006, the Russian government consolidated Sukhoi with several other major aviation organizations, including Mikoyan, Ilyushin, Irkut, Tupolev and Yakovlev, within United Aircraft Corporation, commonly known as UAC. Sukhoi remained a major military-aircraft design and production center inside the new group. Its most prominent contemporary military programs include the Su-35 multirole fighter and the Su-57 fifth-generation fighter. The Su-57 first flew in 2010 and represents Russia’s principal stealth-fighter program. Sukhoi has also promoted the single-engine Su-75, known as Checkmate, although its development and production status remain subject to continuing program decisions. Sukhoi’s civil-aircraft activities were reorganized within UAC. Sukhoi Civil Aircraft was transferred to Irkut at the end of 2018, ceased operating as an independent legal entity after integration approved in 2019, and became a regional-aircraft branch of Irkut in 2020. As a result, the Sukhoi name remains primarily identified with Russian military aviation, even though the wider organization has historically worked across both military and civil aerospace. The company’s current identity is therefore best understood as a defense-oriented aerospace brand and design bureau operating within UAC rather than as a fully independent diversified aircraft corporation.

Pavel Sukhoi’s future design team began taking shape in 1930, when he led a team within TsAGI’s aviation engineering organization. Working under Andrei Tupolev, the team contributed to experimental fighters, bombers and long-range aircraft, including work connected with the ANT-25 and Tupolev bomber programs. In the late 1930s, a Soviet requirement for a multirole combat aircraft led Sukhoi and his colleagues to develop the BB-1 reconnaissance aircraft and light bomber. A government resolution dated July 29, 1939 established the Sukhoi Design Bureau, designated OKB-51, and appointed Sukhoi as its chief designer. The BB-1 entered service as the Su-2, with approximately 910 aircraft produced. During the Second World War, Sukhoi designed the Su-6, an armored ground-attack aircraft intended to replace the increasingly vulnerable Su-2. Although the Soviet government selected the competing Ilyushin Il-2 for mass production, Sukhoi received a first-level Stalin Prize for the Su-6’s development. The bureau also worked on Su-2 variants, the Su-1 and Su-3 fighter prototypes, and the Su-8 long-range attack aircraft. These projects broadened the bureau’s engineering experience even where they did not become major production programs. After the war, Sukhoi became one of the Soviet Union’s early jet-aircraft developers. The bureau worked on mixed-propulsion and jet fighters, including the Su-5 and Su-7, and later developed designs such as the Su-9, Su-11, Su-15 and Su-17. It also investigated bombers, reconnaissance aircraft, artillery-spotting platforms, trainers and transport aircraft. Alongside aircraft designs, the organization developed or applied important aviation systems, including an early booster-control system, drogue parachutes, an ejection seat with a telescoping trolley and a jettisonable pressurized cockpit nose. In 1949, a government decision dissolved the bureau and returned Sukhoi to Tupolev’s organization as deputy chief designer. After Stalin’s death, Sukhoi was permitted to reestablish an independent bureau in 1953 with new production facilities. The organization later developed aircraft that became prominent in Soviet and post-Soviet service, including the Su-7 and Su-17 fighter-bomber families and the Su-25 close-air-support aircraft. The Su-27 and its derivatives subsequently formed one of the most important families in Russian combat aviation, producing numerous air-superiority and multirole variants such as the Su-30 and Su-35. The end of the Soviet Union disrupted the centralized system of design bureaus and production plants. Sukhoi’s associated factories and organizations were privatized or reorganized separately, but the company gradually reconstructed an integrated structure. In the 1990s it diversified into civil aviation and established Sukhoi Civil Aircraft. The broader Sukhoi Aviation Military Industrial Combine included the design bureau, civil-aircraft activities and major production organizations in Novosibirsk and Komsomolsk-on-Amur. Civil projects included the Su-80 utility aircraft, the Su-38 agricultural aircraft and the Superjet regional-airliner program. In February 2006, the Russian government combined Sukhoi with Mikoyan, Ilyushin, Irkut, Tupolev and Yakovlev in United Aircraft Corporation. Sukhoi continued as a major UAC military-aircraft design and manufacturing organization. The Superjet 100 was unveiled in 2007 and first flew in 2008. Sukhoi was also selected to work on carbon-fiber composite wings for the MC-21. The company’s military focus continued through the Su-35 and the Su-57, whose prototype first flew in January 2010. Sukhoi’s civil division was later reorganized. Following the withdrawal of Leonardo from the civil-aircraft business and a UAC restructuring, Sukhoi Civil Aircraft was transferred to Irkut at the end of 2018. Shareholders approved the integration in 2019, and the company became a regional-aircraft branch of Irkut in 2020. Sukhoi therefore remains chiefly associated with military aviation, while civil-aircraft responsibilities sit within other UAC structures. More recent development activity has included the Su-75 Checkmate single-engine stealth-fighter concept. Fires were reported at buildings on the Moscow site of the Sukhoi Design Bureau in February and June 2024; the latter caused substantial structural damage, although officials said the building was not then in use.

A high-performance Russian aerospace and defense brand centered on military aircraft design, advanced fighter technology and export-oriented combat-aircraft programs.

• Su-2Reconnaissance aircraft and light bomber1940

  The Su-2 was Sukhoi’s first major production aircraft. Originally designated BB-1, it was developed in response to a Soviet requirement for a multirole combat aircraft and entered service around the beginning of the Second World War. It combined reconnaissance and light-bomber roles and established the Su designation that later became central to the brand. Approximately 910 aircraft were built.

• Su-25Close-air-support aircraft

  The Su-25 is a heavily protected subsonic attack aircraft designed to provide close air support and battlefield attack. Its rugged configuration, armored systems and ability to operate from relatively austere conditions made it one of Sukhoi’s most recognizable ground-attack platforms. The family includes multiple modernized and export-oriented variants.

• Su-27 familyAir-superiority and multirole fighters

  The Su-27 family is the foundation of Sukhoi’s modern fighter identity. Developed as a long-range air-superiority aircraft, it evolved into a broad group of variants, including the Su-30 multirole fighter and Su-35 advanced multirole fighter. The family is characterized by large airframe volume, long range, high maneuverability and extensive weapons and avionics modernization.

• Su-34Strike fighter

  The Su-34 is a two-seat strike aircraft derived from Sukhoi’s large fighter-aircraft design tradition. It is intended for long-range precision attack and maritime or battlefield strike missions while retaining substantial fighter-like performance. Its side-by-side cockpit and dedicated strike configuration distinguish it from the air-superiority variants of the Su-27 family.
